Plant #1 would locate in a damp and probably contain no undergrowth. Example forest.
Plant #2 would locate in a dry area such as a desert example cactus, as the waxy coating keeps water and the spines suck up water and protect the plany
A plant begin to produce its own food in the following cases:
-when the first leaves are formed
-as soon as photosynthesis starts
Even the little new seeds grown-up from the food reserves, but start making their owm food as they see sunlight
Mitosis is when the cell divides

Cellular respiration<span> is a set of metabolic reactions and processes that
take place in the cells of organisms to convert biochemical energy from
nutrients into adenosine triphosphate (ATP), and then release waste products.</span>
The correct answer between all
the choices given is the second choice or letter B. I am hoping that this
answer has satisfied your query and it will be able to help you in your
endeavor, and if you would like, feel free to ask another question.
Answer:
B. The father did not contribute a sex chromosome to his daughter due to nondisjunction of the sex chromosomes. The daughter is XO and her only X chromosome came from her mother, who was a carrier.
A.The mother's X chromosomes failed to separate during meiosis, and the daughter inherited two X chromosomes with the Lesch-Nyhan mutation. The father contributed no sex chromosomes.
Explanation:
As seen in the question above, a little girl was diagnosed with Lesch-Nyhan syndrome, which is an X-linked recessive condition caused by a mutation in the HPRT1 gene responsible for purine metabolism.
The little girl's parents do not have the syndrome, and no one in the little girl's paternal family presented this syndrome, however, we know that the maternal grandfather of the little girl's mother had the syndrome, which means that it was the mother's genetic material that contributed to the development of the syndrome in the little girl. This was because the little girl did not receive any X chromosomes from her father, but she inherited the two X chromosomes from her mother that coded for the Lesch-Nyhan mutation. This happened because the mother's X chromosome disjuction did not occur during meiosis I.
As shown above, the father did not contribute any sex chromosomes to his daughter, which means that the daughter is XO and her only X chromosome came from her mother, who was a carrier.
